"A lot of people would turn to me for life and relationship advice, to vent, or to break down," Keheler says.

But it wasnt just people he knew that found themselves opening up to him. "I can't even count the number of times Im with a stranger and found myself comforting someone who is pouring their heart out to me," he says.

Once, after spending just 15 minutes with him, a Los Angeles County Sheriff started tearing up and could barely speak about his especially rough day, says Keheler.

Over the years, however, Keheler says he started to hear warning signs from within someone else: himself.

The Catalyst for Change

Unlike all the friends, family members, and random people he met, Keheler says he didn't share his feelings of anxiety and depression. He internalized them. And then the problems began to snowball.

He'd push off everyday to-do items. Procrastination led to more stress. He'd stay in instead of hanging out with friends. He skipped exercising.

Eventually, when Keheler was about 27, his girlfriend called him out on his behaviors. "By not opening up and talking about how I was feeling, it was hurting her," he says.

Keheler says he didnt even realize he was withholding his emotions. "I'd been everyone else's rock for so long that my own mental well-being became a bit of an afterthought."

"Keeping her in the dark led to her feeling doubt and jealousy, because I wasnt being as open with her as she was with me," he says. "I realized that I would lose the one person in my life that mattered the most if I didnt make a change."

The Transformation

"I eventually realized that 'help' can take many shapes and forms," Keheler says. "For me, its about being mindful of my own actions and thoughts. I know now the stressors that set me off, and the best ways I have of fighting back."

The immediate way Keheler fought back was to talk to the friends and family that had turned to him for all those years.

The big change came through how he communicated with his girlfriend (now fiance). Instead of trying to take care of whatever was triggering his anxiety, hed talk through it with her.

The Rewards

Keheler knows he was lucky to have friends and family to support him, and it made him wonder about people who didnt have systems like that in place. "That's when the troubling rise in police suicides in recent years caught my attention," he says.

Blue H.E.L.P a non-profit that brings awareness to law enforcements deaths by suicide recorded more than 600 officer suicides between January 2016 and August 2019.

Keheler has been working on the CBS show S.W.A.T. since 2017, and became a writers assistant for the third season. When he brought up covering this difficult subject on the show, everyone in the room supported it, he says.

"We came to realize that we were uniquely positioned to not only tell a responsible story about suicidal ideation among police officers, but also about the importance of mental health awareness," he says.

That discussion turned into the episode of S.W.A.T. that airs tonight, at 10:00 pm (EST) on CBS, which Keheler wrote, and was created with the National Suicide Prevention Lifeline.

Tonights episode, called "Stigma", starts with the S.W.A.T. team concerned about Bucks (Louis Ferreira) mental health and fear the worst when he goes missing.

The episode is about the warning signs of suicidal ideation, Keheler says: "The psychological traumas that play into it, and the ways to reach out and help loved ones who may be at risk of taking their own life."

Its also about de-stigmatizing the discussion of mental health.

"Every active S.W.A.T. member appears onscreen and speaks openly with a therapist about their feelings, struggles, fears, and more," Keheler says. "We wanted to show that not only is it okay to be vulnerable and openit is normal and essential."

For Keheler, this was an important episode for him to write, he says.

"Having battled depression myself, I know how easy it is to get trapped in that spiral of hopelessness. Without a support system in place, without an outlet ... you can see how many people find themselves venturing down that path."
